Continuous Integration
Continuous Integration (or CI), is what we use to automatically test our code. This is particularly useful to make sure that code in a Pull Request works.
Try pushing your new branch with the fixes to TestRobot and making a Pull Request. You will see something like this at the bottom of the PR (hopefully it will be all green though):

Typically, we will only merge code into the dev or master branches if they successfully build and pass tests, so make sure to build your code before you push it!
